obviously to record you need a microphone but I see what you are getting at.
It would have been helpful if you told us what you intended to record. You may find the “noise” is actually contained in a sound file on the website and you can download the file. Try right clicking on the webpage, look for View Page Source and see if the file is listed in the source files for the page, you may be able to “copy” the file. If it is some streaming sound, perhaps radio or TV for example then you will need some recording software, try something like Audacity or Sound Recorder, both are free. http://www.sound-recorder.biz/download.html and you will find as the last item in the list
or http://audacity.sourceforge.net/
